Abstract: A computer hardware unit, a data center cabinet having the same, and a method of removing the computer hardware unit from the data center cabinet. The computer hardware unit has a housing for placement within a slot of the data center cabinet. At least one of a compute component, a network component and a memory component is provided within the housing. At least one mounting bracket is attached to the housing and to secure the housing to the cabinet. The at least one mounting bracket has a first leg attached to the housing and a second leg for attachment to the cabinet. The at least one mounting bracket is collapsible to change an internal angle between the first leg and the second leg.

Abstract: A rotary machine includes a helical flow compressor/turbine and a permanent magnet motor/generator including a housing with a stator positioned therein. A shaft is rotatably supported within the housing. A permanent magnet rotor is mounted on a shaft and operatively associated with the stator. An impeller is mounted on the shaft and includes an impeller disk with a plurality of impeller blades extending therefrom. The housing includes a generally horseshoe-shaped fluid flow stator channel with an inlet at a first end and an outlet at a second end. The fluid in the generally horseshoe-shaped fluid flow stator channel proceeds from the inlet to the outlet while following a generally helical flow path with multiple passes through the impeller blades. The impeller disk has a plurality of axially-oriented vent holes formed therethrough to minimize a pressure differential across the impeller, thereby minimizing thrust loads applied to the impeller.
